About Ovarian Cancer
Approximately 22,000 women are diagnosed each year with ovarian cancer in the U.S. Ovarian cancer is the fifth most frequent cause of cancer death among women. Despite high response rates to platinum-based chemotherapy in the front-line, approximately 85% of patients will experience disease recurrence. Once the disease recurs, its considered incurable with time to each future recurrence getting shorter. Late-line treatment options for women with ovarian cancer are few, with the proportion of patients achieving an overall response typically less than 10% when treated with chemotherapy.

About Niraparib
Niraparib is an oral, once-daily PARP inhibitor that is currently being evaluated in multiple pivotal trials. GSK is building a robust niraparib clinical development program by assessing activity across multiple tumor types and by evaluating several potential combinations of niraparib with other therapeutics. The ongoing development program for niraparib includes a Phase 3 trial as monotherapy maintenance treatment in patients with first-line ovarian cancer (PRIMA), data from this study were recently presented at the European Society for Medical Oncology Congress (ESMO), a Phase 3 study as a first-line triplet maintenance treatment in ovarian cancer (FIRST), and a Phase 2 study of niraparib combined with bevacizumab maintenance treatment in advanced ovarian cancer (OVARIO).

Several combination studies are also underway, including trials of niraparib plus pembrolizumab in metastatic, triple-negative breast cancer and advanced, platinum-resistant ovarian cancer (TOPACIO). Janssen Biotech has licensed rights to develop and commercialize niraparib specifically for patients with prostate cancer worldwide, except in Japan.

Important Safety Information

Zejula may cause serious side effects, including:

Bone marrow problems called Myelodysplastic Syndrome (MDS) or a type of blood cancer called Acute Myeloid Leukemia (AML). Some people who have ovarian cancer and who have received previous treatment with chemotherapy or certain other medicines for their cancer have developed MDS or AML during treatment with Zejula. MDS or AML may lead to death.
